Krohn, T. C., Hansen, A. K., Dragsted, N.

Abstract

The study revealed significant differences in systolic and diastolic blood pressure, heart rate and body temperature between rats housed in the tree conditions, indicating that both grid floors and plastic floors are more stressful for the animals than bedding. The observed differences did not diminish over the two-week observation period.
